JULIAN DEMATTEIS, OF BATAVIA, IOWA.

RAILWAY-TIE.

Application filed May 18, 1910.

To all whom it may concern:

Be it known that I, JULiAN DnMivr'rnis, a citizen of the United States, residing at Batavia, in the county of Jefferson, State of Iowa, have invented certain new and useful Improvements in Railway-Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway ties and has for an object to provide a combined cement and metal tie having novel means for securing the traflic rails, this means being formed simpler and with less labor than usual in devices of this character.

A further object is to provide a one-piece metal tie and rail securing means.

With the above ends in view, the invention consists of the novel details of construetion and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawing forming part of this specification, Figure 1 is a plan view of a railway tie constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view taken on the line 2 2, Fig. 1. Fig. 3 is a cross sectional View taken on the line 3-3, Fig. 1.

The reference character 10 designates a metal railway tie, this tie being formed from a single sheet of metal bent longitudinally upon itself and the side portions then bent toward each other as shown at 11 and the meeting edges of these side portions crimped or seamed as shown at 12. The tie thus formed is triangular in cross section and has its apex slightly flattened so that no sharp edges are presented to lacerate the hands of the workmen laying the t-ie. The tie is filled with a cement filling element 13, recesses 1S being formed in this element which conform in contour to the rail seats or recesses formed in the metal tie as hereinafter described.

Formed in the apex of the tie adjacent each end is a recess 14, formed by transverse slits 15 in the inclined sides 16 of the tie, these slits extending from the apex to a point a short distance below the apex. The apex is slit longitudinally as shown at 17 Specification of Letters Patent.

and 19, thus forming six opposing tabs, four approximately rectangular and two approximately triangular each tab 18 being bent downwardly toward the base of the tie and when in this position forming a support for the bottom surface of the rail baseflange. The opposed edges of the tabs 18 overlap above the longitudinal seam 12 in the base of the tie if left their normal length, and it is preferable to leave them this length as the machining of the tie is thus reduced to a minimum. The slits 19 nearest the center of the tie are inclined obliquely to the long diameter of the tie, this construction permitting of a V shaped projection 2O overhanging the tabs when the latter are bent to their horizontal or operative position and presenting a stop which engages the inner face of the rail and positively prevents the vertical displacement of the rail base flange seated upon the tabs, and also prevents the collapsing outwardly of the rail.

In mounting the traffic rails, the latter are slid lengthwise into the recess formed by bending downward the tabs as above described, and thus may expand during the warm weather and contract during cold weather without injury to the tie.

It will be noted that the tie and rail securing means are formed from a single piece of sheet metal without rivets, bolts or other fastening means being employed to secure any of the meeting parts in position, and further that the cement filling element when in position will prevent abnormal vibration of the metal tie when a train is passing thereover.

That is claimed is:

A triangular railway tie formed from a blank of met-al bent longitudinally upon it self and the side portions thence bent toward each other and their meeting edges secured together', said tie being slit adjacent its apex to form tabs and an angular projection, said tabs being bent to horizontal position and underlying said angular projection, and a plastic material filling element within the tie.

In testimony whereof, I affix my signature, in presence of two witnesses.
